讲座题目：The Berge-Fulkerson coloring for Kochol superposition snarks

讲座简介：
It is conjectured by Berge and Fulkerson that every bridgeless cubic graph has six perfect matchings such that each edge is contained in exactly two of them. The Berge-Fulkerson conjecture holds for 3-edge-colorable cubic graphs. A snark is a cyclically 4-edge connected cubic graph of girth at least 5 admitting no 3edge coloring. In this talk, the Berge-Fulkerson conjecture is verified for an infinite family of cyclically 6-edge connected superposition snarks constructed by Kochol. This is a joint work with Siyan Liu and Cunquan Zhang.
